The production process commences with the meticulous preparation of raw materials. High - grade stainless steel or specialized alloy sheets are sourced for constructing the furnace body, chosen for their excellent corrosion resistance, strength, and durability. Insulation materials, such as high - density ceramic fiber boards or refractory bricks with low thermal conductivity, are also procured. These materials play a vital role in minimizing heat loss and maintaining the integrity of the internal temperature and atmosphere.
In this section, the raw materials undergo cutting and shaping operations. CNC (Computer Numerical Control) cutting machines are employed to precisely cut the steel sheets into the required shapes and sizes for the furnace body components. Advanced laser cutting technology may be utilized for more intricate cuts, ensuring high precision and accuracy. The insulation materials are also cut and shaped to fit snugly within the furnace structure, providing optimal thermal insulation.
2.2 Component Manufacturing Area
2.2.1 Furnace Body Fabrication
The fabricated steel components are then assembled to form the furnace body. Welding is a critical process here, with highly skilled welders or automated welding robots using techniques like TIG (Tungsten Inert Gas) or MIG (Metal Inert Gas) welding. These methods ensure strong, airtight welds that are essential for maintaining the sealed environment of the furnace. After welding, the furnace body undergoes surface treatment, including grinding and polishing, to remove any burrs, irregularities, and to enhance its corrosion resistance.
2.2.2 Heating Element Production
High - performance heating elements, typically made from materials such as nickel - chromium (Ni - Cr) alloys or iron - chromium - aluminum (Fe - Cr - Al) alloys, are manufactured in a dedicated area. The production process involves extrusion, winding, and heat - treatment to shape the elements and optimize their electrical and thermal properties. Stringent quality control measures are in place to ensure that each heating element meets the required specifications for resistance, temperature - bearing capacity, and durability.
